Abstract

This research aims to obtain morphological character of Matoa (Pometia pinnata JR Forst & G Forst) plant. This research had been conducted from April to October 2021, in 5 Regency (Karanganyar, Klaten, Pati, Sukoharjo, and Surakarta) Central Java. The morphological characther based on direct observation through primary and secondary data recording, and documenting parts of an adult matoa plant with purposive random sampling. Data of morphological characterization of matoa was analyzed using descriptive analysis method with assistance of Ntsys v2.02i program. The results showed a morphological diversity of matoa plant accessions. Fifty (50) matoa accessions exhibit morphological diversity in plant height, canopy diameter, stem circumference, branching type, leaf colour, number of leaflets, compound leaf length, compound leaf petiole length, leaflet width, fruit density, fruit length, fruit weight, seed weight, and fruit skin colour.

Abstract

Today, smallholder forests in West Java - Indonesia play an important role as suppliers of domestic and industrial wood needs. However, with forest managers who are not yet professional and the easy conversion of land use into non-forest, smallholder forests cannot guarantee the sustainability of wood supply. In supporting the implementation of sustainable forest management in smallholder forests, understanding is needed regarding the characteristics of smallholder forests. The purpose of this study is to evaluate the characteristics of smallholder forest stands as a basis for assessing the sustainability of wood raw material supply. The research location is smallholder forest in Sumedang district. Data collection method is a purposive sampling method with moving plot. The results indicated that the density of smallholder forests per ha was 342.5 trees per ha, with 14 species of trees. The distribution of tree diameters ranges from 1-49 cm, with a predominant class diameter of 10-15 cm. The potential stands for smallholder forests are 32.68 m3ha-1. The cutting felling cycle is at the age of 6.5 years with a selective logging system at a diameter size of more than 15 cm, so it is not optimal and there is a tendency that it will not continue. Therefore, in increasing its sustainability, it is necessary to increase the cutting life. So, there is a tendency for community forest areas to be converted into other land uses.

Abstract

Land degradation is a major constraint to agricultural productivity, with drylands particularly vulnerable to critical conditions. Sorghum (Sorghum bicolor L. Moench) is a promising crop for such environments due to its adaptability and dual-purpose value for both biomass and sugar-rich stalks. This study evaluated the growth and yield response of four sorghum varieties—Super, Suri, Numbu, and Keller—to different rates of compound NPK fertilizer under dryland conditions. The experiment was arranged in a Randomized Complete Block Design (RCBD) with two factors: sorghum varieties and five fertilizer doses (0, 10, 12, 14, and 16 g plant⁻¹), replicated three times. Data were subjected to ANOVA, and treatment means were compared using DMRT at the 5% significance level. Results showed that the Keller variety consistently produced the best agronomic performance, including plant height, number of leaves, stem segments, stem diameter, and biomass dry weight. Moreover, Keller combined with 12 g plant⁻¹ of NPK fertilizer produced the highest sap content (14.0% Brix), highlighting its potential as a dual-purpose sorghum. Leaf traits were most responsive at 14 g plant⁻¹, indicating that moderate-to-high fertilization enhances vegetative growth without excessive input. These findings demonstrate that varietal selection coupled with appropriate nutrient management is crucial for optimizing sorghum production in dryland systems. The study provides practical guidance for farmers and can inform future breeding and fertilizer recommendation programs for sustainable sorghum cultivation.

Abstract

Phalaenopsis hybrid is one of the orchids that is very important in the horticultural market as an ornamental plant whose demand continues to increase. This causes the need for breeding in order to obtain new varied flower characters as desired by polyploidization. Polyploidy induction in Phalaenopsis hybrids was carried out using colchicine. The purpose of this study was to determine the karyotype pattern of Phalaenopsis hybrids. The research was conducted at the Screenhouse of the Faculty of Agriculture and Integrated Laboratory Unit of Sebelas Maret University, Surakarta in August 2021-March 2022. Polyploidy induction was carried out by dripping 1500 ppm concentration of colchicine on flower bud of Phalaenopsis hybrid. The method used in this research is squashing. The experimental results showed that the karyotype pattern in control Phal. Golden Tree was 2n=3x-7=50m, while in Phal. Fuller Sunset and Phal. OX X-ray was 2n=4x=76m. The karyotype pattern in orchids with colchicine induction was Phal. Golden Tree 2n=6x-14=100m, while in Phal. Fuller Sunset and Phal. OX X-ray 2n=8x=152m.

Abstract

Pest attacks are one of the main obstacles in the cultivation of long beans (Vigna unguiculata ssp. sesquipedalis) in Indonesia. This study aims to evaluate the effectiveness of cyanide acid content from various parts of the rubber cassava plant (Manihot glaziovii) in controlling Aphis craccivora pests and its impact on the growth and yield of long beans. The study was conducted in Sragen and the Laboratory of the Faculty of Agriculture, Tunas Pembangunan University, Surakarta during September–December 2024 with a completely randomized block design (RAKL) with two factors, namely plant parts (leaves, tuber skin, and tubers) and extract doses (0, 10, 20, and 30 ml/plant). The results showed that tuber skin fermentation (B2) was the most effective in reducing the percentage of pest attacks (30.80%) and attack intensity (40.44%). The treatment dose of 30 ml/plant (K4) gave the best results in suppressing pest attacks and increasing growth and yield parameters, such as plant length (141.64 cm), fresh stalk weight (1905.77 g), and fruit weight (497.22 g). The bioactive content in cassava tuber skin has the potential as a pest control agent as well as a plant growth stimulant. This study supports the use of environmentally friendly and sustainable local biopesticides to increase the productivity of long beans.

Abstract

Recent herpetological collections have added several new taxa to the previously compiled herpetofauna of Pakistan. This paper presents annotated and updated checklists of 243 species, 104 genera, and 27 families of extant herpetofauna, including 24 anuran amphibian species, belonging to 4 families. In comparison, the reptilian fauna consists of 219 species/subspecies, including 2 species of crocodiles, 15 species of turtles and tortoises, 119 species of Sauria, and 83 species of snakes belonging to 23 families. Four species of amphibians and 33 species of reptiles are endemic to Pakistan. Separate checklists of prehistoric reptiles (50 taxa) for both dinosaurs (26 taxa) and non-dinosaurian taxa (24 taxa) are also presented here. This review article is based on previous literature on the herpetofauna of Pakistan. It will serve as a baseline for future work related to the herpetofauna of Pakistan, which is essential in biodiversity research.
